Brake Maintenance

Servicing the Brakes

Before each use, check brakes on both a level surface and
slope.
Always set the parking brake when you stop the machine
or leave it unattended. If the parking brake does not hold
securely, an adjustment is required.
Checking the Brakes
1. Park the machine on a level surface, disengage the
blade control (PTO).
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Apply the parking brake. The wheels must lock when
you try to push the machine forward.
4. If the wheels do not lock, adjust the brakes. Refer to
Adjusting the Brakes.
5. Release the brake and press upper control bar very
lightly, approximately 13 mm (1/2 inch). The wheels
should rotate freely, if not; refer to Adjusting the
Brakes.
Adjusting the Brakes
The brake lever is on the upper control bar. If the parking
brake does not hold securely, an adjustment is required.
1. Park the machine on a level surface, disengage the
PTO, and set the parking brake.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Check the brake before you adjust it; refer to Checking
the Brakes.
4. Release the parking brake; refer to Releasing the
Parking Brake in Operation.
5. To adjust the brake, rotate the wing nuts on the brake
rods (Figure 39). Turn the wing nuts clockwise to
tighten the brake and counterclockwise to loosen the
brake.

Important: With the parking brake released, the
rear wheels must rotate freely when you push the
mower. If brake action and free wheel rotation
cannot be achieved contact your service dealer
immediately.
